The watching skua

Wherever there are penguins, Southern (Great) Skua gulls are never far away: there's one up there in the note! It may seem unkind, nasty, brutal and all that, but skuas live largely on penguin chicks and eggs. They do have to eat too, after all! And when they aren't harassing penguins they (and Giant Petrels) do a good job of clearing the beaches of carrion such as dead seals.
